Well, making libgcc use a host-side target macro again certainly isn't the 
right fix.  Why is EH_FRAME_SECTION_NAME differently defined when building 
c-cppbuiltin.c and when building libgcc2.c?  Whatever the cause is, you 
should fix the host-side build so that __LIBGCC_EH_FRAME_SECTION_NAME__ 
doesn't get defined inappropriately (probably meaning that 
EH_FRAME_SECTION_NAME isn't defined when building c-cppbuiltin.c).
